Be more specific about rust version

[NobbZ]

I tried to compile and run colonize from master a couple of minuets ago, but it does not work, I do get different error messages depending on the toolchain used to compile, I will give an excerpt below:

But lets start with the toolchain versions I tested:

$ multirust run nightly rustc --version
rustc 1.10.0-nightly (4ec5ce5e4 2016-05-12)

$ multirust run beta rustc --version
rustc 1.9.0-beta.2 (87cb73304 2016-05-04)

$ multirust run stable rustc --version
rustc 1.8.0 (db2939409 2016-04-11)

Now the failure I do get when trying to compile stable or beta:

   Compiling colonize_world v0.0.1 (file:///home/NobbZ/projects/rust/colonize/world)
   Compiling rgframework v0.0.1 (file:///home/NobbZ/projects/rust/colonize/framework)
   Compiling colonize v0.0.2 (file:///home/NobbZ/projects/rust/colonize)
src/action.rs:3:30: 3:39 error: `#[derive]` for custom traits is not stable enough for use and is subject to change (see issue #29644)

                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and nightly does emit the following stuff:

   Compiling rayon v0.3.1

[... many other messages tagged [E0277] ...]

^C

The very same error appears never the less when I use the command as specified in the README or a plain cargo run.

Very interesting.

For me it compiles on both nightly:

─── multirust run nightly rustc --version
rustc 1.10.0-nightly (2b79e05a0 2016-05-13)
─── multirust run nightly cargo build --no-default-features --features nightly 

and stable:

─── multirust run stable rustc --version
rustc 1.8.0 (db2939409 2016-04-11)
─── multirust run stable cargo build

I'm not sure about beta, but it should be compiling on stable and nightly for you.
Can you post the exact cargo build/cargo run commands you used?

EDIT: See below regarding stable.

[indiv0]

Actually, regarding your nightly build. That's an issue with rayon that was specific to the 2016-05-12 nightly so if you update to 2016-05-13 it should compile.

As to your stable and beta builds, it still looks to me like you used the wrong build commands.

EDIT: See below regarding stable.

[indiv0]

That said, the project could definitely use more information regarding which rustc versions are compatible. That should be fixed when I fix #3 and #7 by adding travis-cargo to the .travis.yml and when I add the relevant information to the README.md when I fix #13.

[indiv0]

Actually testing the build on stable results in the same errors that you got. My fault for assuming it worked (it did work just a few days ago!).

Looking into it now.

[NobbZ]

Commands for building/running where simple as cargo run/build...

And on nightly?

[NobbZ]

Plain as on stable/beta and copy pasted the ones from the README.

OK. I've found the issue and I'm working to correct it now.

At the moment, if you update to the latest nightly you should be able to compile with cargo build --no-default-features --features nightly, but compilation on stable and beta is broken.

[NobbZ]

After I had to purge and reinstall rustic because of former
selfdesintegration of multitude I'm already trying on latest nightly. It's
only a couple of minutes now...

@NobbZ #51 should fix compilation on stable and beta. Try it and let me know.

[NobbZ]

Ok, I checked commit 3e88676 from master since you already merged #51, and I can build from all relevant toolchains now.

Thank you!

You're welcome! Let me know if you have any further questions or issues.
